Dissertation completed in partial fulfillment of the requirements for the degree of Masters of Science in Materials Science and Engineering at the Kazuo Inamori School of Engineering, New York State College of Ceramics at Alfred UniversityThe titanium-niobium oxide compositional system shows potential for application in a variety of technologically important material systems. However, this system is not well understood. In this study, a titanium niobium mixed-phase system was prepared via the sol gel method and characterized as a function of heat treatment temperature. Differential thermal analysis, thermogravimetric analysis and high temperature X-ray diffraction (HTXRD) were used to characterize the mixed-phase system. The purpose of the current investigation is to gain insight into the phases and their structural characteristics present in the phase-mixed system. To do so, the system was studied using three approaches. First, the influence of the titanium to niobium metal ion ratio on the phase assemblage was examined. Next, the influence of composition on crystallization temperature was determined. Finally, the influence of composition and heat treatment temperature on phase transformation temperature and assemblage was investigated. This approach suggests that the precursor materials and heat treatment regiment affects the phase assemblage.113 pagesen-USThesis
